As soon as you start learning Vue you find out that the atomic unit of its architecture are components. In fact, that’s nothing Vue-specific: any component-based technology, such as React or Angular, work the same way.

One day you start creating a Vue application. You start creating components in order to structure the different pieces of your application. That’s cool and you should be feeling the great dev experience of Vue and the web component architecture. As you go on with your project you start to somehow structure your application components, probably by pages and components.

As your application grows, you start to look for performance patterns to make it faster. On the way, you’ll find code splitting and lazy loading to be two of them that make your initial bundle smaller by deferring the loading of code chunks until needed.

When building applications you often come across the case where you need to design a list or search interface for the user. They usually manage lots of data, thus you need a way for the user to show it “in chunks” so that we keep the application performance and the data organized.

In the CSS world, we can see plenty of great preprocessors that improve the language, being SASS/SCSS, LESS and PostCSS the most common among them. SASS seems to be still the most popular and used solution by the date of writing, and that’s no surprise since it’s fully featured and extends the CSS language with an easy to understand syntax.
